Return of UltramanEdit
Kingsaurus III was a dinosaur who survived the extinction and now feasts on nuclear energy and Uranium 235. Appearing on a mountain, it was quickly confronted by MAT and shot down Hideki Go's Arrow 2 with its highly radioactive U-235 beam. Go called upon Ultraman Jack and a fight ensued. Kingsaurus III's barrier quickly reflected all of Jack's attacks, even the Cinerama shot, said to be ten times more powerful than the Wide Shot. After the blocking, Kingsaurus advanced; using his horn beams to blind Jack while stabbing his knee and his waist. Finally, exhausted, Jack collapsed, and Kingsaurus III escaped through burrowing.
In the hospital, Go became horrified of the beast, and later escaped the hospital to train himself to jump over Kingsaurus III's barrier and attack it. After training several times with his broken leg, he finally managed to learn the comet kick and was ready to put it in action. Meanwhile, MAT received a telegram signaling that Kingsaurus III appeared at a nuclear power factory. Go soon followed and tried to jump over the beast's barrier. Failing, he called upon Ultraman. Jack looked at the monster that had defeated him. Calculation led him to conclude that all of Kingsaurus's powers came from his horns. Realizing that, Jack used Go's jump to kick off kingsaurus III's horns. A short beating later, Jack used his Specium Ray to kill Kingsaurus III once and for all.
